Titel:

No signs of life after flashing EFI chip

Tekst:

I got an eBay macbook pro and the seller stated only the backlight was bad. I had a spare display sitting around so I figured it would be an easy way to put together myself a working 17 inch. [br]
 
 
[br]
 
 
When I got it, I had discovered there was also an EFI password on it. Unable to return it, I wanted to try to reclaim the situation somesituation, and I followed this guide: https://gist.github.com/willzhang05/e5b5563cdc65514dfb7ca131e03ca4b2 [br]

Everything went well from reading the chip to writing the modified firmware back on. Once I reconnected everything, I plugged the charger in, and NOTHING! UGH[br]
 
 
[br]
 
 
No light on the charger (tried a few now), no lights on the battery level indicator, no signs of life when trying to power it on. [br]
 
 
[br]
 
 
I tried a spare magsafe board and no change. All of the small components around the EFI chip are still present.[br]
 
 
[br]
 
 
Did applying 3.3v to the efi chip without removing it from the board fry something, or did I somehow knacker something else? I figured since the guides I saw online still had the chip on the board, I would be fine doing the same.[br]

I have no idea where to start : ([br]
